Method/Apparatus/Procedure:
   The synthetic method was used. A Reichert microscope, type RCH, equipped with a heating stage was used as described elsewhere.1 The disappearance and reappearance of the interface between (1) and (2) could be observed without difficulty.

Source and Purity of Materials:
   (1) Baker Chemical Co.; reagent, No. 9011; n(20 °C, D) = 1.3445, d(20 °C, 4 °C) = 0.780.
   (2) Synthesized by transesterification of methyl esters and acetates using sodium methanoate as catalyst; purified by gas-liquid partition and thin-layer adsorption chromatography.

Estimated Errors:

   Temperature: ± 0.5 K.
